Trumaine Johnson returns to Jets after mystery incident

Wednesday’s benching still remains a mystery, but high-priced cornerback Trumaine Johnson returned to practice with the Jets on Thursday.

Johnson missed Wednesday’s practice due to what Todd Bowles repeatedly called “an in-house matter” — or, presumably, for disciplinary reasons with a likely fine involved.

However, Johnson was a full participant a day later and has said he expects to play in Sunday’s season finale against the Patriots.

Both Johnson and Bowles have declined to divulge what transpired that led to the corner’s benching for a day.

Johnson, who turns 29 next week, is in the first year of a five-year, $72.5 million deal ($34 million guaranteed). He has had an up-and-down season with Gang Green, despite producing a team-best four interceptions.

Johnson also has missed five games due to a quad injury and committed his share of bad penalties — including a pivotal pass-interference call in overtime during Sunday’s loss to the Packers.

“Throughout the whole year I think he made some plays, and I think he had some plays he’d like to do over. So, as a whole, he’s been solid,” Jets defensive coordinator Kacy Rodgers said.
