WASHINGTON -- The Washington Nationals say Bryce Harper has a "significant" bone bruise in his left knee but no ligament damage, and general manager Mike Rizzo is hopeful the star outfielder will be back this season.
Harper injured his knee when he slipped on first base in the first inning of a rain-delayed game against the San Francisco Giants on Saturday night. Rizzo said Sunday that Harper had an MRI afterward that showed no structural damage.
"Although we feel we've dodged a bullet a bit here with any long-term ligament and tendon damage, the bone bruise is something of significance, and we're going to treat him cautiously and hopefully have him back later on this season," Rizzo said. "We put ourselves in a position that we can treat it cautiously and we'll continue down that road."
Rizzo says there's no timetable for Harper to return. The team is placing him on the 10-day disabled list and activating outfielder Michael Taylor.
Harper, the 2015 National League MVP, is having another spectacular season for division-leading Washington, hitting .326 with 29 home runs and 87 RBIs.
Rizzo -- and anyone watching the play -- feared it was a serious, potentially season-ending injury. Harper clutched at his left knee and didn't put any weight on it as he was helped off the field.
"We were all holding our breath last night a little bit and hoping for the best," Rizzo said. "Got a glimmer of hope last night when he was able to walk up the stairs from the dugout to the clubhouse and put some weight on it. Had some optimism."
Rizzo cautioned that "the bone bruise is real" and that the team has the luxury of being extra cautious because of its 14-game lead in the NL East. Given injuries to Harper, Stephen Strasburg -- who has a rehab assignment Monday -- and others, the Nationals' focus is getting healthy for the playoffs.
Rockies: Bettis to return after cancer diagnosis
MIAMI -- Colorado Rockies right-hander Chad Bettis will complete his comeback from chemotherapy for testicular cancer by starting Monday night's game in Denver against Atlanta.
The 28-year-old Bettis finished his last round of treatment in May, two months after doctors discovered his testicular cancer had spread. He had surgery in November to remove the cancer, but it returned and he was forced to leave the team in March for chemotherapy.
The Rockies announced before their game Sunday at Miami that Bettis will rejoin the rotation.
"To see where he was when he was re-diagnosed, it was hard for us, because he was a big part of our team," manager Bud Black said. "To see him go through what he has had to go through, and to see him work his butt off -- a guy who had chemotherapy, and how that feels -- to where he is now, what a great story for all of us. It has been just wonderful to watch."
The game will be Bettis' first since Sept. 30. He went 14-8 for the Rockies last year.
Marlins: Michael Jordan to have small stake in team after sale
MIAMI -- A person familiar with the situation says NBA Hall of Famer Michael Jordan has a small stake in Derek Jeter's investment group that reached an agreement to buy the Miami Marlins.
The person confirmed Jordan's role to The Associated Press on condition of anonymity Sunday because the parties involved have not commented.
Jordan already owns the NBA Charlotte Hornets. He and Jeter have known each other for more than 20 years and are close friends.
A signed $1.2 billion agreement was submitted Saturday to Major League Baseball for Marlins owner Jeffrey Loria to sell the franchise to a group that includes Jeter, the former New York Yankees captain. Venture capitalist Bruce Sherman of Naples, Florida would be the controlling owner.
The Marlins expect to close the deal in early October.
