Indians pitcher Justin Masterson will need a few more days to determine his status for the rest of the year, according to FoxSports.com.
Masterson left his last start with a rib injury, and was evaluated Tuesday. If he remains symptom free over the next few days, he'll likely to be able to return during the regular season. If Masterson still experiences symptoms in a few days, he's unlikely to return.
Masterson has a 3.52 ERA in 189 1/3 innings.
