ALLEN PARK, Mich. -- The Detroit Lions have brought back defensive tackle C.J. Mosley from suspension and are activating linebacker Kyle Van Noy from the short-term injured reserve list, coach Jim Caldwell said Monday.
Mosley had been suspended and sent home from London the day before the Lions' Week 8 game against Atlanta, with the team saying it was suspending him for two weeks. Nine days later, Detroit has chosen to reinstate Mosley.
Mosley apologized Monday, although he declined to say what the suspension was for. ESPN NFL Insider Chris Mortensen, citing sources, reported that Mosley was sent home after disconnecting a smoke alarm at the Intercontinental Hotel in London and being caught with marijuana when security checked on the disconnection.
"I'm not going to speculate on any details involving the situation I was involved in," Mosley said. "It's been handled accordingly and I just want to apologize to the organization and my teammates, to my fam and fans about what happened. I just look forward to getting back on the field and getting back to the grind and getting back to work."
Mosley refuted the report, saying "it ain't what it is, but at the same time I got to take responsibility for it."
Caldwell also declined to comment on Mosley's suspension other than to say it was a group decision to ban him.
"I'm not going to go into if it is true, if it's not true, all those things, I'm not going to respond to it," Caldwell said Monday. "It wasn't released from our organization."
Caldwell said any further punishment from the NFL would be deemed a "league matter."
Van Noy will be activated after missing the first eight games because of core muscle surgery following a sports hernia suffered in the preseason. The linebacker was the team's second-round pick in May out of BYU. Detroit traded up to nab Van Noy and expected him to be a starter prior to his injury. He'll compete with Ashlee Palmer for the starting SAM linebacker spot when he does return.
Van Noy has been practicing with Detroit for the past two weeks.
"He's been moving around," Caldwell said. "Now we'll immerse him a little bit more in the details of preparation and we'll see where it goes. He looks good. He's performed well so we'll see how that works."
Mosley is expected to slide into the starting defensive tackle slot opposite Ndamukong Suh.
To make room for both players, the Lions waived tight end Jordan Thompson and safety Jerome Couplin on Saturday.
Detroit (6-2) leads the NFC North by one game over the Packers.
