Cushing did not practice on Wednesday to receive extra rest, according to Texans head coach Bill O’Brien.
According to the report, Cushing has had his knee drained several times over the past couple of weeks and could be out until Week 11, when Houston plays the Cleveland Browns.
After the road game against the Titans on Sunday, the Texans return home to face the Philadelphia Eagles before having their bye week.
Cushing suffered a torn ACL to the same knee in 2012. His season also ended early last season when he broke his fibula and tore the lateral collateral ligament in the knee.
“I think in dealing with a lot of these guys over the years that are coming off of knee injuries, that first year back, it always takes them a while to get back into the swing of things," Texans coach Bill O'Brien said, according to ESPN.com. "I think if you look back at some of the guys I've dealt with that have come off of knee injuries, maybe it is eight, nine games into it where they're truly trusting their knee and they're full-speed."
Cushing, the 2009 NFL Defensive Rookie of the Year, has 54 total tackles and one sack in seven games this season for Houston (3-4), who have lost three games in a row.
