Miami Dolphins linebacker Zach Thomas underwent knee surgery on Friday.

The successful procedure was performed to repair a tear of the lateral meniscus in his left knee. Thomas will begin rehab and will be evaluated just before the team begins training camp on July 31. The five-time Pro Bowl selection has led the Dolphins in tackles in seven of the past eight seasons, including the 2003 campaign when he made 184 stops -- 113 of which were solo. He also had three interceptions, two fumble recoveries and one sack last season.
