The former American League Rookie of the Year said after a start last week he was working to regain explosiveness to regain some of his velocity, according to Beck. Multiple reports throughout the spring have said Fulmer has lost velocity on his fastball. The move to sideline Fulmer will be an attempt to correct that issue.
Spencer Turnbull will start in place of Fulmer in Friday's game against the Rays.
Fulmer went 3-12 with a 4.69 ERA across 24 starts last season, his worst as a Major Leaguer. Following a 2015 trade with the New York Mets, Fulmer broke into the league by winning Rookie of the Year honors in 2016, when he went 11-7 with a 3.06 ERA and 132 strikeouts.
