6. LaDarrell McNeil, Tennessee safety (neck instability): Sustained Aug. 27 -- out indefinitely (likely for season).
Who is he? McNeil, a senior starter at safety, finished fourth on the team in tackles last season with 76. He has 31 career starts, 22 straight before this injury. McNeil had two interceptions in 2014 and forced a fumble against Alabama. The injury "came kind of out nowhere," Tennessee coach Butch Jones told reporters. "Very, very unfortunate. I feel for him."
Next man up? Sophomores Todd Kelly Jr. and Evan Berry are the backup safeties, so one of them presumably would replace McNeil. Kelly had 33 tackles and three interceptions in 2014. Berry, whose older brother Eric Berry is a former Vols All-American, made five tackles in limited action. Evan Berry ranked second in SEC kickoff return average last season (29.5 yards).
Outlook? If Evan can play like Eric, Tennessee will be fine. But this is another injury for the Vols. Read on for how rough summer practice has been in Knoxville.
5. Rashaan Gaulden, Tennessee defensive back (broken foot): Announced Aug. 22 -- out for season.
Who is he? A sophomore, Gaulden was working as the starting nickel back. That's an important position because the Volunteers play more nickel defense against spread offenses than their base 4-3 package, as noted by the Knoxville-News Sentinel. He also was an effective special teams player as a gunner in kick coverage. "Rashaan meant so much to us, not just from a DB standpoint, but from special teams as well," Jones told reporters.
Next man up? According to the Sentinel, junior Malik Foreman, who made 10 tackles in 13 games last season, likely will replace Gaulden. But he won't be the only one up for extra snaps, as junior college transfer Justin Martin should be in the mix if he can make up for lost time. Martin, who chose Tennessee over LSU and Ole Miss, suffered a knee injury earlier in camp and missed two weeks.
Outlook? Tennessee doesn't have much time to get its secondary ready. Oklahoma visits Knoxville on Sept. 12 for a nonconference game that could gauge which program is on its way back to elite status.
4. Marcus Jackson, Tennessee offensive lineman (torn bicep): Announced Aug. 11 -- out indefinitely (likely for season).
Who is he? A fifth-year senior, Jackson was expected to be the Vols' starting left guard. He wasn't a star, but he's a former SEC All-Freshman member who started 12 games in 2014 and whose loss is shaking up Tennessee's offensive line.
Next man up? Adding to the problem is reserve guard Austin Sanders, who also tore his bicep and likely is done for the season. The Vols have gone from having four returning starters to only two set spots along the line. Redshirt sophomore Brett Kendrick has worked at left guard, moving over from starting right tackle. Jashon Robertson will likely start at one guard spot. "The good thing and the positive thing going in is we've recruited to have some depth at the offensive line position," Jones told reporters. "Obviously, it does set us back."
Outlook? Losing offensive linemen in preseason camp is never ideal. Tennessee has recruited well in recent years, but it's still a lot of young talent. The Vols need all the depth they can get if they're really going to be SEC East contenders.
