CLEVELAND -- Indians president Chris Antonetti isn't sure how long Leonys Martin will be sidelined after the outfielder was placed on the 10-day disabled list with a non-baseball-related condition Thursday.
Antonetti said Martin, who became sick Tuesday night and didn't play in Wednesday's 5-2 win over the Minnesota Twins, could be out for longer than 10 days.
"He's got an illness that he's working through," Antonetti said. "It happened really quickly. After the game the other night, he just didn't feel well. We're now in the process of getting him assessed and working through the best way to get him healthy."
Antonetti wouldn't say whether Martin had been hospitalized. Manager Terry Francona said before Wednesday's game that Martin was dealing with an intestinal issue.
Martin is batting .333 with two home runs and four RBIs in six games since being acquired from the Detroit Tigers at the trade deadline. He is hitting .255 with 11 homers and 33 RBIs overall in 84 games.
Outfielder Greg Allen was recalled from Triple-A Columbus.
The Indians have been dealing with injuries to outfielders all season and hoped adding Martin would provide stability. Additional moves for an outfielder might be made before the Aug. 31 trade deadline for players who have cleared waivers.
"We'll continue to spend the month of August looking for opportunities to improve our team," Antonetti said. "What impact Martin's condition or illness has on that, we're not yet sure."
Antonetti expects outfielder Lonnie Chisenhall, who has played in only 29 games because of calf injures, to return this season. Outfielder Tyler Naquin had surgery on his right hip Friday and could be back before the season ends.
