The Toronto Blue Jays' slow start is being hampered further by injuries.
Toronto Blue Jays pitcher Mat Latos will start this weekend against the Los Angeles Angels.
There should be an update soon from the team regarding Happ's timetable for a return.
On the bad news end, Ken Rosenthal is reporting that Josh Donaldson will miss 2 to 4 weeks with his calf injury.
Donaldson batted.310 with two homers and four RBIs in nine games prior to going on the disabled list.
The Blue Jays also said injured right-hander Aaron Sanchez had a portion of nail removed from his right middle finger during a procedure performed by Dr. Glenn Goldstein in Kansas City. The Sanchez move, due to a nagging blister issue, was made Sunday but retroactive to Saturday.
Happ is coming off a career season in 2016, posting a 20-4 record with a 3.18 ERA and a 1.17 WHIP over 195 innings pitched.
The left-hander exited Sunday's game against the Baltimore Orioles because of soreness in his elbow. He underwent an MRI on Monday and has been diagnosed with inflammation in his left elbow, according to TSN's Steve Phillips.
It remains to be seen what roles the two players will have after their spot starts but if Happ or Sanchez's injuries persist for an extended period of time, John Gibbons and the staff will have to make a decision on who to keep in the rotation.
The Blue Jays recalled right-hander Danny Barnes and infielder Ty Kelly from Triple-A Buffalo.
