The Detroit Lions received difficult injury news Tuesday morning before their latest training camp practice.Head coach Dan Campbell told reporters that tight end Anthony Firkser suffered a broken fibula during Mondays padded practice. Running back Sione Vaki broke his nose and is expected to miss a little while.Neither players exact recovery timetable has been announced.Anthony Firkser Injury Further Depletes Tight End RoomFirksers injury is the more serious of the two setbacks.The veteran tight end left Mondays practice with what was initially described as a leg injury. Campbells update confirmed a broken fibula, putting Firksers roster chances in major doubt.Detroit was already thin at tight end. Rookie Miles Kitselman is expected to be out for a while with his own leg injury, which prompted the Lions to sign Nick Muse and release wide receiver Tarik Black.The position entered camp with Sam LaPorta, Brock Wright, Tyler Conklin and several players competing for depth roles. Firksers injury removes another experienced option from that competition.Detroit may now need to add another tight end simply to maintain enough healthy players for practice.Sione Vaki Will Miss Time With Broken NoseVakis injury was initially reported as an eye issue after he left Mondays practice.Campbell clarified Tuesday that Vaki suffered a broken nose. The third-year running back will be sidelined temporarily, though Campbells wording suggests Detroit does not expect a lengthy absence.Vakis value stretches well beyond the offensive backfield. The Lions consider him one of their top special-teams players, and he entered camp behind Jahmyr Gibbs and Isiah Pacheco in the running back rotation.With Gibbs still not practicing, Vakis absence temporarily removes another option from Detroits backfield.Bottom LineThe Lions first padded practice produced two confirmed injuries.Anthony Firkser suffered a broken fibula, adding another serious concern to an already depleted tight end room. Sione Vaki broke his nose and will miss some time, though his absence appears more likely to be measured in days or weeks than months.Detroits next roster move may be easy to predict.Brad Holmes may need to find another tight end before the Lions return to full-speed work.The post Dan Campbell Announces Significant Injury Updates Sione Vaki and Anthony Firkser appeared first on Detroit Sports Nation.
