Justin Morneau has been placed on the 15-day disabled list “as he continues to recover from a concussion that he suffered on July 7,” according to the Minnesota Twins’ official website.

Morneau was attempting to break up a potential double play at second base, when he was accidentally kneed in the head.

This is Morneau’s second trip to the disabled list with concussion symptoms in his career. In 2005, he was hit in the head by a Ron Villone pitch that subsequently landed him on the DL.

Justin will be eligible to come off the disabled list on July 23. 

Despite fantasy baseball owners only missing their starting first baseman for a week, it comes at a crucial time in the season.

With week 15 shortened due to the All-Star break, head-to-head owners were hoping Morneau’s stellar first half numbers carried over into the shortened week, to cash in on a quick head-to-head victory.

Morneau currently leads the majors in on-base percentage (.437), is second to Miguel Cabrera (.346) with a .345 batting average, has blasted 18 homers, and has driven in 56 runs.
