After taking a leave of absence in February, defensive end Arden Key is back at LSU, the school confirmed in a statement.

In May, LSU coach Ed Orgeron said he expected Key, who had shoulder surgery, to be back by the start of summer classes on June 5.

“Arden had shoulder surgery and everything went as planned,” Orgeron said in a press release. “We are looking forward to having Arden rejoin the team tomorrow (Monday).”

Key did not participate in any drills in the spring and left for “personal reasons” prior to the start of practice. The Atlanta native dropped out of school in the spring semester for unspecified reasons.

The 6-foot-6 defensive lineman holds LSU’s record for most sacks in a regular season with 12 sacks in the 2016 season.

Key is expected to be anchor for defensive coordinator Dave Aranda, and is considered one of the best defensive players in college football. The junior has 17 career sacks through his first two season.
