Arian Foster on Wednesday posted a picture of an MRI of his hamstring on Twitter, prompting questions about the severity of his injury and his openness about it. "This is an MRI of my hamstring, The white stuff surrounding the muscle is known in the medical world as anti-awesomeness," he wrote, providing a link to a picture of the MRI image.

Texans running back Arian Foster will be ready to play in Week 1 of the regular season. Foster strained his left hamstring on Saturday night in a preseason game against the 49ers, but the NFL's reigning rushing champion says the injury in mild and improving. "I'm okay," Foster said. "It's a lot better than I thought it was. I'm already jogging." Foster's strained hamstring that cost him two weeks of camp is worse than the one he suffered Saturday. "It's never a good thing to have experience with hamstring problems, but, unfortunately, with my track record, I do," he said. "It was just a mild strain. It feels good."

The Texans have agreed to a contract with veteran receiver Bryant Johnson. After practice Monday, Johnson worked out for the team's pro personnel people and impressed them enough to get an offer.

Texans coach Gary Kubiak is optimistic Arian Foster will be ready for the regular-season opener. Foster re-aggravated a hamstring injury in Saturday's preseason game in San Francisco. The NFL's leading rusher in 2010, Foster left the field in the first quarter of Houston's 30-7 victory, favoring the left hamstring that he strained early in training camp. "Looks like we're dealing with the same thing we were dealing with at the start of camp," coach Gary Kubiak said. "Hopefully, we can get him back on the rehab train, and get him ready for opening day. He'll be day to day."

Texans running back Arian Foster left Saturday night's preseason game against the 49ers with a hamstring injury. Foster has been dealing with a hamstring injury for a majority of training camp and he's unlikely to play in Houston's preseason finale next week. He posted a message on his Twitter account Sunday morning, thanking fans for their concern and criticizing the negativity coming from fantasy football owners. "4 those sincerely concerned, I'm doing ok & plan 2 B back by opening day. 4 those worried abt your fantasy team, u ppl are sick," he wrote.

Texans running back Arian Foster led the NFL in rushing last season, but he won't holdout in hopes of getting a new contract. Foster is scheduled to make $525,000 with Houston this season. "I grew up where sometimes the lights weren't on or sometimes we didn't eat dinner at night. You know, my daughter lives well, my wife lives well and I live well," Foster said. "I believe in karma. You take care of the universe; the universe takes care of you. You can't run around thinking negative all the time. You neither."

Texans coach Gary Kubiak is very confident that quarterback Matt Leinart has a place in the NFL. Leinart said recently that he still wants to be a starter in the league. He signed on with Houston to serve as Matt Schaub's backup. "First off, I think he's a leader," Kubiak said. "He's got that 'It' factor that people seem to gravitate to." Kubiak said that Leinart will play a lot on Monday night against the Jets. "I know what he's going through as a quarterback," Kubiak said. "I've had some that have been through that process before. It's tough to be successful in this league but I watched his confidence come back last year and I watched how our team reacted when he would go in when Matt [Schaub] missed a little time or something, he would go and practice or do whatever; they never wavered and I see that going on in practice right now. "It's fun, I hope he gets his career going again and plays 10 or 12 years and comes back as a starter. 'That's what we all want for him."

Matt Leinart still believes he has a future as a starting quarterback in the NFL. Leinart, the 2004 Heisman Trophy winner, signed with the Texans to serve as Matt Schaub's backup. He could have signed with the Seahawks and reunited with former USC coach Pete Carroll. "I did what was best for me, and this is the best fit for me, by far," Leinart said. "I still want to be a starter, that's my goal. I'm still young. I've still got a lot of ball left."

Texans running back Arian Foster, the NFL's rushing champion last season, left practice early Friday after straining his hamstring on a 40-yard touchdown run. Houston coach Gary Kubiak said he was uncertain about the severity of the injury. "I don't know, but he didn't feel good, so I just said 'get out,'" Kubiak said. "He went 35, 40 minutes and looked great, so I'm hoping he'll be right back out there. We'll see."

Texans wide receiver Andre Johnson dislocated his left index finger during a Tuesday morning practice. Johnson was running a slant route in an individual drill and leaped to catch a pass, with rookie cornerback Rashad Carmichael defending. He couldn't make the catch and came down shaking his left hand. "We're getting it looked at," coach Gary Kubiak said. "I've got a big lump in my throat like everybody else, but hopefully, he'll be fine."
