Cedar Rapids Kernels infielder Jonatan Hinojosa has received a 50-game suspension for violating baseball's drug policy.

Bob Nightengale, Major League Baseball columnist for USA TODAY Sports, reported via Twitter Saturday afternoon that Hinojosa tested positive for metabolites of Nandrolone, an anabolic steroid. Phil Miller, who covers the Twins for the Minneapolis Star-Tribune, also reported the suspension via Twitter.

Hinojosa, now listed on the Kernels' "Restricted" list, joined the Kernels from the Twins' extended spring training camp just a week ago when outfielder Jeremias Pineda was placed on the club's Disabled List. He played in just one game during his week with the Kernels, going hitless in three at-bats against Peoria April 23.

Hinojosa and Randy Rosario, who was placed on the Kernels' Disabled List Friday, have been replaced on the Cedar Rapids roster by outfielder Ivory Thomas and right-handed pitcher Todd Van Steensel.

Hinojosa, 21, is from the Dominican Republic. He was signed as a non-drafted free agent in 2009.
