The 49ers just announced linebacker Kwon Alexander tore his pectoral muscle Thursday night against the Arizona Cardinals and likely will have season-ending surgery next week.
Tough blow. Alexander was the heart of the defense, and a play maker. This season, he has 34 tackles, two tackles for loss, one quarterback hit, half of a sack, one forced fumble, four pass breakups and an interception. Opposing quarterbacks completed only 36.4 percent of their passes when targeting Alexander. He’s an excellent player, especially in pass coverage.
As a run defender, Alexander is small and misses lots of tackles. This season, he missed 11 tackles in eight games.
