MIAMI -- Lewis Brinson's tenure on the disabled list is going to last longer than initially anticipated. The Marlins announced on Friday the rookie center field is dealing with a right hip bone bruise, and he will be out several more weeks.
The revised prognosis was made after Brinson was examined by team physician, Dr. Lee Kaplan. The 24-year-old has been on the 10-day disabled list since July 4.
Initially, it was called a right hip inflammation.
With Brinson out, Cameron Maybin and Yadiel Rivera are handling center field.
"It's just one of those things that's going to take a little bit of time," Marlins manager Don Mattingly said. "We have to be careful with how we bring him back. It's not going to be long term, if we take care of it properly. We have to give it time to heal."
One of the centerpieces in the offseason trade of Christian Yelich to the Brewers, Brinson anchored center field from Opening Day until he last played on July 3. The Coral Springs, Fla., native has a slash line of .186/.232/.338 with 10 home runs and 30 RBIs in 89 games.
Although he has had struggles, Brinson also has shown signs of improvement. In his final seven games before going on the DL, his slash line was .269/.321/.423 with a home run.
"We know that bone bruises take time to heal," Mattingly said. "Brins is a guy we definitely want to make sure we take care of properly, so he can finish the season being 100 percent healthy. And keep going with the strides that he's been making. I'm looking forward to finishing the season with him."
Worth noting
• Catcher J.T. Realmuto was reinstated from the paternity list on Friday, with catcher Chad Wallach being optioned to Triple-A New Orleans. Realmuto's wife, Lexi, gave birth to a girl, Gracie Laine, on Tuesday morning. The All-Star catcher was back in the starting lineup in the series opener with the Phillies on Friday.
During his time on the paternity list, Realmuto watched every inning of the Marlins-Brewers series while he was in the hospital. On Wednesday, Yelich, who came up through the Marlins' system with Realmuto, visited the hospital. Yelich had the entire Brewers team sign a card congratulating Realmuto and his wife.

"He came and saw us at the hospital," Realmuto said. "The whole Brewers team signed the card. They wrote, 'Make sure you take your full three days.' They underlined three like four different times."
Yelich and Realmuto have been together every step of their professional careers, and the two are All-Stars this year for the first time.
"I feel like it's only fitting that we get to experience our first All-Star Game together," Yelich said. "It's kind of a way for it all to come full circle, from two 18-year-old kids first talking about just trying to make it to the big leagues, to this."
• Sandy Alcantara (right axillary infection) and Tayron Guerrero (left lumbar strain) continue to long toss. Alcantara will continue his progression in Jupiter, Fla., during the All-Star break and will need at least one rehab assignment before being reinstated.
• Garrett Cooper made the start in left on Friday against Phillies right-hander Jacob Arrieta. Mattingly said Cooper will alternate in left field with Derek Dietrich and with Justin Bour at first base.
"Coop is going to get his share of at-bats at left and first," Mattingly said. "The rotation we use -- they all kind of play two out of three."
