"They're not members of our program anymore, and we wish them the very best going forward," Riley said.
Bridges and McGowan were identified as suspects in an alleged armed robbery after a 911 caller accused them of robbing him of marijuana on April 15 at his apartment in Norman, Oklahoma.
Police searched Bridges' apartment the day after the alleged incident and reported that they recovered a handgun, drug paraphernalia, and "a bag of green substance appearing to be marijuana."
No charges have been filed in relation to the alleged incident, but the investigation remains open, notes Nolan Clay of The Oklahoman. McGowan and Bridges have both denied any involvement.
The Sooners suspended both players indefinitely after being made aware of the matter. Bridges and McGowan missed Oklahoma's spring game on April 24.
McGowan reportedly entered the transfer portal in April after the allegations surfaced. He rushed for 330 yards and three touchdowns to go with 201 receiving yards as a freshman in 2020.
Bridges caught nine passes for 101 yards and two touchdowns during his time at Oklahoma.
