David Ross (concussion) has reported improvement and could begin working out soon.
Ross will be examined on Monday in hopes of being cleared to resume workouts. The catcher has missed the last week of action with concussion-related symptoms.

Jacoby Ellsbury is not in the Red Sox' lineup Sunday.
Ellsbury had played every inning of every game to this point, so the club finally decided to give him a breather. The outfielder is batting just .189/.268/.230 in May. Shane Victorino is handling center field Sunday, while Daniel Nava is in right.
Shane Victorino (back) is back in the Red Sox' lineup Sunday.
Victorino sat out the last two games after his back tightened up on him, but he's ready to give it a go. He's starting in center field with Jacoby Ellsbury getting a day off.
Stephen Drew (back) is sitting out for the second straight game Sunday.
Drew was able to play through a minor back issue on Friday, but the Red Sox don't want to push him. He should be ready to roll again soon. Pedro Ciriaco is getting another start at shortstop.
Craig Breslow picked up his first win of the season by tossing 1 2/3 scoreless relief innings against the Twins Saturday.
Breslow missed the first five weeks of the season with shoulder inflammation and has posted a 1.35 ERA over seven appearances since his activation. The 32-year-old Yale graduate has never finished a season with an ERA higher than 3.75 and boasts a 2.97 career number. Nerds don't often fool scouts, but Breslow has made it look easy.

David Ortiz was 3-for-4 with two homers and six RBI in Boston's 12-5 rout of the Twins on Saturday.
Ortiz hit a three-run shot in the top of the first inning, a run-scoring single in the top of the third and a two-run bomb in the top of the seventh. The veteran designated hitter has regressed some from his hot start but is still sporting an outstanding .362/.408/.681 batting line with seven homers and 29 RBI in 24 games.
Ryan Dempster allowed five earned runs over 4 2/3 innings but the Red Sox beat the Twins on Saturday.
Dempster was let off the hook by the Boston offense, which rattled off 12 runs in a rout of Minnesota. Dempster yielded eight hits and six walks, throwing only 68 of his 127 pitches for strikes. He now has a pedestrian 4.27 ERA and 1.31 WHIP in 52 2/3 innings, though we wouldn't give up on him quite yet because the strikeout rate is tremendous. Dempster will face the Indians next.
