PHOENIX -- D-backs manager Kirk Gibson corroborated the prognosis of left fielder Mark Trumbo, specifying that the length of his absence due to a stress fracture in his left foot might be even longer than the six weeks Trumbo predicted.
"The summary I got on it confirmed six to eight weeks probably," Gibson said. "He's got a boot on there with something on it called a bone enhancer that sends some stimulation down there. I know that he had [an injury] previously on the other foot and that was lengthy. We don't expect that to be that lengthy."
In 2011, when Trumbo was with the Angels, he suffered a break of the tarsal navicular near the rear of his right foot, a much more serious injury. The results this week of an MRI and CT scan on Trumbo's left foot revealed a stress fracture of the third metatarsal bone at the top of the foot.
"That one is a serious, serious thing," Trumbo said about the previous injury. "That's a career-ender under certain circumstances. It's not a fun one. This is a fairly common injury with runners, you can look it up online. It's pretty cut and dried what you have to do to come back."
The D-backs placed the left fielder, who leads the team with seven homers and 19 RBIs, on the 15-day disabled list on Thursday before the final game of a four-game series against the Cubs in Chicago.
Trumbo began feeling the effects of the injury during Monday night's game at Wrigley Field and an MRI revealed the extent of the damage. He saw D-backs orthopedic specialist Dr. Michael Lee, who administered the CT scan on Friday, and expects to see a couple of other specialists in the upcoming days.
Trumbo suffered the injury to his right foot during his rookie season and played more than a month on it before he was disabled near the end of September. He returned to play 144 games in 2012.
Trumbo was obtained by the D-backs this past offseason in a deal with the Angels that sent pitcher Tyler Skaggs to Los Angeles. It was anticipated that he would bolster the lineup and augment power displayed by first baseman Paul Goldschmidt. Despite hitting .210 with a .264 on-base percentage in 21 games, Trumbo was already doing just that.
