Arkansas opened its summer training camp on Thursday, officially kicking off their 2017 season.

However, the Razorbacks did so without two key players fully participating, according to coach Bret Bielema.

Bielema, speaking to reporters after the first camp session, said LB Dre Greenlaw and WR Jared Cornelius aren’t quite at full strength as they continue to rehab injuries:

Cornelius caught 32 passes for 515 yards and four touchdowns in 2016 and is expected to play a bigger role in Arkansas’s offense this fall.

Similarly, Greenlaw has high expectations for this coming season as well after recording 43 tackles in seven games last season.
