Due to a bad back, the Hawks’ guard could be out for a while: “Word that Marvin Williams could be out for weeks with a lower back injury swept through the Hawks’ locker room like a storm before Monday’s game against New Orleans at Philips Arena. ‘Man, that’s a tough pill to swallow right there,’ Joe Johnson said. ‘Every time we get over one hurdle it seems like another one pops up.’ Williams sustained the injury late in Saturday’s home win over Detroit and was held out the entire fourth quarter. He is scheduled to see specialists this week, Hawks coach Mike Woodson said, and his status will not be updated until after those visits. ‘This is a huge blow,’ Woodson said before Monday’s game. ‘Marvin’s been such a big part of what we’re doing. So we’ll have to regroup and find ways to deal with it until we can get him back out there.’”
