Sharpton tore his right quadriceps muscle against the Jacksonville Jaguars on Oct. 30, 2011 and will make his return against those very same Jaguars on Sunday after being activated by the Texans from their physically unable to perform list. To make room for Sharpton, the Texas waived safety Troy Nolan.
Sharpton first practiced two weeks ago and due to his placement on the PUP list was not eligible to play until after week six. Though his quadriceps injury should have been healed and ready by the preseason, Sharpton had a setback with a hip injury early in training camp. But now he is ready to go for a Texans team that needs depth at linebacker with Brian Cushing out and Tim Dobbins questionable for Sunday's game, leaving Bradie James and Barrett Ruud as the only healthy linebackers.
