Pittsburgh Steelers star T.J. Watt is due to undergo scans for hip and knee injuries, according to Pro Football Talk.
Following Sunday's 16-16 tie with the Detroit Lions, head coach Mike Tomlin told reporters that Watt would require further evaluation for the two injuries.
A groin injury kept the three-time Pro Bowler out of Pittsburgh's Week 3 24-10 loss to the Cincinnati Bengals.
Injuries weren't much of a problem for Watt through his first four seasons as he missed a total of two games. Over that span, he established himself as one of the NFL's most fearsome pass-rushers, a status cemented by his four-year, $112 million extension.
