Following Monday's 4-1 loss, the club announced via Twitter that Colon will be placed on the bereavement list and right-hander Gonzalez Germen will be recalled from Triple-A Las Vegas in advance of Tuesday's series opener at Oakland.
Right-hander Carlos Torres started in Colon's place on Monday and worked five scoreless frames in a no-decision. Before the game, Collins said he hoped to get four, maybe five innings out of Torres, who threw two pitches and recorded one out on Sunday.
Torres didn't find out he was going to start until he got to the stadium on Monday morning. It was his first start since last September, and this outing was his longest of the season. He went about it carefully.
"You start with one and hope you get through one and go from there," Torres said. "Because that very easily could have been two innings and out of the ballgame with eight runs. So you have to go with one inning no matter what, whether you're starting or relieving."
As a long man in the Mets' bullpen, Torres has thrown up to 81 pitches in 4 2/3 innings. That outing came on July 4, when starter Jon Niese left after one out. Torres also managed four innings (63 pitches) on June 15.
