Toronto Blue Jays veteran right-hander Max Scherzer said Wednesday he plans to consult additional doctors after forearm tendinitis has failed to respond to treatment and MRI results have revealed no clear structural explanation for his continued discomfort.

Scherzer, 41, was placed on the injured list April 27 following five rough starts in which he posted a 9.64 ERA and failed to complete the third inning three times.

"I can still tell there's something off in my arm," Scherzer told reporters after a throwing session at Tropicana Field. "It's as confusing as anything I've ever had because, usually, you go get an MRI, you would see something. There's no strains; there is no inflammation per se. So I'm going to have to talk to more doctors to figure out a course of action here."

Blue Jays manager John Schneider offered little clarity on a return timeline.

"It's kind of cloudy right now," Schneider said. "There's no real firm timetable as to when he's going to really start getting after it. I think we'll know more in a couple of days."

On a positive note, Scherzer said left ankle inflammation that had also been bothering him has cleared up and is no longer a concern.

The three-time Cy Young Award winner is in his 19th MLB season under a one-year, $3 million contract that includes up to $10 million in performance bonuses tied to innings pitched starting at 65. He carries a career record of 222-120 with a 3.26 ERA and 3,499 strikeouts, ranking 11th all time and just 10 behind Hall of Famer Walter Johnson.

Scherzer started Game 7 of last year's World Series for Toronto, one of three postseason appearances that included a victory over Seattle in the AL Championship Series.
