Raiders head coach Josh McDaniels said Wednesday that he isn't concerned about Waller's (undisclosed) continued absence from practice, Paul Gutierrez of ESPN.com reports. "He's doing everything he can to get back out there," McDaniels said. "I see him every day. He's in every meeting."
That said, Tashan Reed of The Athletic relays that McDaniels declined to make a prediction about Waller's status for the Raiders' Sept. 11 regular-season opener against the Chargers. McDaniels' unwillingness to commit to Waller being available for Week 1 makes it safe to conclude that the tight end is unlikely to play in Friday's preseason finale against the Patriots.
