The former Defensive Rookie of the Year tore his ACL in 2012 and broke his fibula and tore his LCL in the same knee seven games into the 2013 season.
On Wednesday, Cushing tweeted he is ready to go in 2014.
After Cushing was injured in 2012, the Texans' defense fell apart; last season without him, they compiled the worst record in the NFL.
"I'm just looking forward to playing football again," Cushing said Tuesday on SiriusXM NFL Radio, per CSN Houston. "Getting back, playing the game I love and putting forward a full 16 games."
It's fair to wonder, however, if after two knee surgeries Cushing will ever return to the dominant player he once was.
When healthy, Cushing has the size, speed and sideline-to-sideline ability to gobble up ball carriers and is solid in pass coverage. In his last full season (2011), Pro Football Focus ranked him as its third-rated inside linebacker.
