Raiders interim head coach Rich Bisaccia said Waller (ankle) is day-to-day and will remain in Las Vegas during the team's Week 8 bye to receive further treatment, Adam Hill of the Las Vegas Review-Journal reports.
Prior reports have classified the injury that kept Waller out of Sunday's 33-22 win over the Eagles as an inner ankle/heel strain, and while the team hasn't confirmed that diagnosis, Bisaccia noted that the tight end isn't believed to have suffered any structural damage. The fact that the Raiders are describing Waller as day-to-day rather than week-to-week seemingly bodes well for his chances of being ready to go following a well-timed Week 8 bye. Foster Moreau (six receptions for 60 yards and a touchdown on six targets) filled in capably as the team's starting tight end Week 7, but the Las Vegas offense would surely benefit from having its top pass catcher in Waller available for a Week 9 matchup with the Giants on Nov. 7.
