Michael Crabtree is expected to play for the first time since tearing his Achilles in the spring.

"I'm really ready to play," Crabtree said from his locker Friday. "It's been a long time coming."

"I feel comfortable enough to play," Crabtree added. "I feel great."

Crabtree emerged as a legitimate No. 1 receiver after Colin Kaepernick took over for Alex Smith last season.

Aaron Dobson has been ruled out of Sunday's game by the New England Patriots against the Houston Texans.

Dobson suffered a foot injury in the Patriots' win over the Denver Broncos last Sunday.

Kenbrell Thompkins took Dobson's spot in the second half of the game.

Zac Stacy is expected to play on Sunday for the St. Louis Rams against the San Francisco 49ers.

Stacy is coming back from a concussion in last week's game.

Stacy has 624 yards on 141 carries and four touchdowns.

Percy Harvin is dealing with issues again on his surgically repaired hip.

Harvin is seeing doctors on Saturday and his status for Monday's important matchup between the Seattle Seahawks and New Orleans Saints is in doubt.

Michael Crabtree has been activated by the San Francisco 49ers from the physically unable to perform list.

Crabtree has practiced over the past three weeks and is expected to be in the lineup on Sunday against the St. Louis Rams.

Colin Kaepernick had a strong game against a week Washington Redskins' defense, finding Anquan Boldin for two touchdowns and one for Vernon Davis.

The Philadelphia Eagles will start Nick Foles moving forward, a decision that has appeared obvious for weeks.

Chip Kelly had been waiting on anointing Foles as the starter indefinitely until Michael Vick was healthy again.

Foles has completed 63.6 percent of his passes with 16 touchdowns and no interceptions this season.

Aaron Rodgers' odds of playing in Week 13 against the Detroit Lions are "slim and none."

Rodgers injured his collarbone several weeks ago against the Chicago Bears.

The Green Bay Packers will instead start Matt Flynn.

The Washington Redskins will not have Jordan Reed in the lineup on Monday against the San Francisco 49ers due to a concussion.

Reed suffered the concussion in Week 11.

Reed has 45 catches for 499 yards and three touchdowns this season as he has been one of the NFL's most productive tight ends.

Reed was a third round pick in 2013.

The Indianapolis Colts will leave Trent Richardson as their lead running back despite his struggles and the strong play of Donald Brown.

"We don't plan on changing our rotation with our backs," said Pep Hamilton. "We've always been a running back by committee bunch, so we're going to continue to do that."

Brown has 21 more yards on half of the carries Richardson has had since the trade.

The Colts have defended Richardson's poor play.

Wes Welker is probable for Sunday's game between the Denver Broncos and the New England Patriots.

Welker has passed all the tests from independent neurologists necessary for him to play.

Welker signed with the Broncos this offseason after spending six seasons with the Patriots.
