Harbor (calf) intends to run Tuesday with the expectation of returning to practice Wednesday, the Jaguars' official site reports. "It's getting better," he said. "It's not 100 percent, but I think it's getting to the point where I can do some explosive stuff." Marcedes Lewis' high ankle sprain will hold him out 6-to-8 weeks, leaving a void at tight end in Jacksonville. If Harbor can fend off the strained calf that has kept him off the field since July 28, he's the prime TE option to factor into the passing game. Although he's never been targeted more than 40 times in his four NFL campaigns, he's coming off a season in which he hauled in 24 catches (on 35 targets) for 292 yards and two touchdowns. Assuming active status is achieved Sunday versus the Colts, his looks should experience a modest uptick.
