BOSTON -- Red Sox outfielder Daniel Nava was placed on the 15-day disabled list with a left wrist sprain before Saturday's game against the Royals.
It is Nava's second stint on the DL this season. He missed 21 games from July 29 to Aug. 19, also with a left wrist sprain.
In a corresponding roster move, the Red Sox activated left-hander Felix Doubront (right knee) from the 15-day DL.
Doubront is scheduled to start Sunday's game against the Royals. He is 10-6 with a 4.70 ERA in his first full season as a starter. The southpaw has 119 strikeouts in 122 2/3 innings.
Doubront is winless in his last four outings and has not won since July 18.
Nava is hitting .250 with 17 doubles, four home runs and 27 RBIs in 67 games for the Red Sox this year.
Trade gives Red Sox players chances to play
BOSTON -- On Saturday afternoon, the Red Sox finalized a deal to send Adrian Gonzalez, Josh Beckett, Carl Crawford and Nick Punto to the Dodgers. That deal has opened up chances for playing time across the diamond and in the rotation.
"You would think that without Josh here there is an absolute starting rotation situation," manager Bobby Valentine said. "Without Adrian there is an absolute fist base situation. Nick Punto was signed to a two-year contract to be our utility backup infielder, that's open for grabs. Left field seems to be what it was most of the year but it was always more temporary than it is now, as far as the opportunity is concerned."
The Red Sox recalled promising shortstop Jose Iglesias, outfielder Che-Hsuan Lin and right-hander Junichi Tazawa from Triple-A Pawtucket before Saturday's game against the Royals.
Iglesias was hitting .329 in 19 games for Pawtucket this month. He had a brief stint with the Red Sox in early May, but did appear in a game, though he played in 10 games for Boston in 2011. Iglesias is rated as Boston's No. 11 overall prospect by MLB.com.
"He's here kind of because we needed an extra infielder for [Saturday]," Valentine said. "I don't have that plan [going forward] yet."
Pedro Ciriaco, who started at third on Saturday, will continue to play multiple positions in the infield.
Lin hit .247 with two homers and 30 RBIs in 107 games for Pawtucket. He joins the Red Sox for the third time this season. Lin has appeared in six games with Boston, starting once.
Tazawa is also on his third stint with the Sox. He has a 1.37 ERA and one save in 20 appearances with Boston this year.
The Red Sox also acquired first baseman James Loney from the Dodgers. He was not with the team on Saturday but is expected to be in uniform for Sunday's game against the Royals.
"He's a good defender, he's very durable, he's played a lot," Red Sox general manager Ben Cherington said. "We think he's got a pretty good swing for Fenway. I think he's excited to hit in a different ballpark."
Mauro Gomez started at first base for the second straight game on Saturday. He made the most of his opportunity -- belting his first career homer over the Green Monster in his first at-bat.
Gomez and Loney are expected to both spend time at first base.
"Not a real strong plan yet," Valentine said. "If we have James here in uniform, he'll definitely be part of that plan."
Fans can take photos, run bases at Fenway
BOSTON -- Fans can be photographed with a Red Sox player during On-Field Photo Day on Sunday, before a scheduled 1:35 p.m. ET game with the Royals at Fenway Park. Fans can line up on the warning track from 11:45 a.m. to 12:30 p.m, weather permitting.

The Red Sox honored 11 athletes with ties to New England who participated in the 2012 Summer Olympics in a pre-game ceremony.
The list of Olympians included gold medalists Aly Raisman (gymnastics), Tina Charles (women's basketball), Asjha Jones (women's basketball) and Kayla Harrison (judo).
The Red Sox entered Saturday's game leading the American League with 365 runs, 349 RBIs and 656 hits at home.
Left-hander Rich Hill made his sixth Minor League rehab appearance on Friday, striking out two in a 1-2-3 inning for Triple-A Pawtucket. Hill is on the mend from a left elbow strain.
