Brian Cushing has been cleared to begin training camp with the Houston Texans.

Cushing is recovering from a torn ACL.

Cushing suffered the injury when taking a low hit from Matt Slauson.

Veteran backup QB Sage Rosenfels, who was cut by the Vikings before last season, announced his retirement Sunday on his Facebook page.

He said he will soon file his paperwork with the NFL to make his retirement official.

"Like most NFL players, I wish I could have played a couple more seasons, but usually the league is done with you before you are done with it," he wrote.

Some within the Houston Texans' organization have privately suggested that Andre Johnson has conceded that he has lost a half-step now that he is almost 32.

The importance for the Texans to finally develop a reliable young No. 2 receiver is significant.

DeAndre Hopkins is slated to become that receiver.

Johnson had 112 catches and 1,598 yards in 2012.

Brian Cushing believes teammate J.J. Watt could go down as the best defensive player in NFL history.

"The things that he's going to be able to accomplish are unbelievable," Cushing told ESPN.com's John Clayton last week on the "Inside The Huddle" podcast. "When you talk about the potential that he has of really being the greatest defensive player ever, he could be."

Watt had an extraordinary season in 2012 and was named Defensive Player of the Year.
