The Cincinnati Bengals placed wideout John Ross on injured reserve Wednesday because of a right shoulder injury sustained during Monday night’s loss in Pittsburgh.

No surgery was scheduled, and Ross is expected back this season, according to NFL Network. A team can reinstate two players each season from injured reserve after sitting out at least eight weeks.

In a corresponding move, the Bengals signed rookie receiver Stanley Morgan Jr. from their practice squad. He joined the team after going undrafted out of Nebraska.

Ross had his arm in a sling after the 27-3 loss, which dropped the Bengals to 0-4. The team has been without star wideout A.J. Green since training camp, and Green is expected to miss a few more games.

Ross, 24, was having a breakout season after disappointing through two years since being drafted ninth overall in 2017. He has 16 catches for 328 yards and three touchdowns in four games, although he has cooled off with just five catches for 58 yards over the last two.

The speedster played in just three games as a rookie in 2017, not catching a pass, and then missed three games in 2018. He finished with 21 catches for 210 yards and seven touchdowns last season.
