The injury news isn’t all good — but it isn’t all bad, either. After playing without four of their rotation players in the win over the San Antonio Spurs, the Detroit Pistons could be getting at least one of them back. Guard Avery Bradley practiced on Tuesday and after missing seven games because of groin injuries, could be back to face the Heat in Miami on Wednesday. Well, maybe. Coach Stan Van Gundy was optimistic on having Bradley back, but cautioned waiting until Wednesday morning to gauge the impact of a practice on Bradley’s body. “The test of all those things is the next day,” Van Gundy told reporters after Tuesday’s practice. “(Wednesday) morning, we’ll know if it went well. He was good out here and didn’t have to pull himself out (Tuesday). “You just don’t know how he’s going to feel coming through.” The Pistons (20-15) have gone 5-2 in the games Bradley has missed, with Reggie Bullock and Luke Kennard filling in. They’d love to get their second-leading scorer (15.7 points) back from injury and be able to bolster their wing corps, as well as their perimeter defense, especially with Reggie Jackson also out until at least mid-February. The news wasn’t as good about forward Stanley Johnson, who has a strained hip flexor. Jackson didn’t go through practice and Van Gundy classified Johnson’s status as doubtful, at best. It’s a small step forward, as the Pistons were down to their last few roster options on the wing, with two-way player Luis Montero getting a call-up from the Grand Rapids Drive of the development league as a backup. Bradley’s return would be a boost, but given the nature of his injury, he likely wouldn’t be expected to defend at the same level, as his lateral movement could take some time to get back to normal, having not played in almost three weeks. Van Gundy noted how they’ve had to manage defensively without Bradley, but losing Jackson compounded the issue. A smaller Ish Smith presents some other considerations.
