Before Wednesday's game, the Tigers announced that the 25-year-old had been optioned to Triple-A Toledo. It was announced as the corresponding roster move made in the wake of the the team's decision to activate closer Francisco Rodriguez from the family emergency medical leave list.
Manager Brad Ausmus said the move was not related to Monday night's incident in his pregame press briefing prior to Wednesday's game.
"It has nothing to do with the other night," Ausmus said. "He was scuffling, we had K-Rod coming back and we felt like we could use an extra pitcher for the foreseeable few days, at least through the weekend."
Collins, who did not play in Tuesday's 5-1 loss to the Oakland A's, incurred the wrath of Tigers fans the previous day when he made an obscene gesture toward the jeering crowd after losing a ball in the lights in Monday's series-opening victory.
Cameras caught him not only flipping the bird but also yelling vulgarities after he was taunted for his misplay in center field.
After the game, Collins apologized repeatedly, saying he "lashed out," acted inappropriately and should've handled himself with more maturity.
Although there was precedent for supplementary discipline -- MLB suspended former Philadelphia Phillies closer Jonathan Papelbon for a lewd gesture toward the crowd in September 2014 -- the league chose not to suspend Collins. It is not immediately clear whether Collins was fined, as the league does not comment on fines.
After Monday's game, manager Brad Ausmus expressed his disappointment and said that if necessary, the incident would be handled "internally."
