Cobb (elbow) will start Friday against the Blue Jays, Marc Topkin of the Tampa Bay Times reports.
Friday will mark Cobb's first major league action since 2014, as the 28-year-old is finally at the end of his lengthy recovery from Tommy John surgery. The results have been somewhat rocky during his rehab stint, as he's worked to a 6.60 ERA over four starts at Triple-A and a 6.75 ERA in four starts at High-A, so the Rays will likely play it fairly cautiously with not much on the line in the final month. Tampa is expected to go with a six-man rotation for the time being, so no further changes to the rotation are forthcoming.
