JACKSONVILLE, Fla. -- Jacksonville Jaguars linebacker Telvin Smith has left the team to be with his family after his brother was killed in a Sunday night shooting in Valdosta, Georgia.

According to Valdosta Police Department Chief Brian Childress, 25-year-old Brian Keith Moore was shot to death shortly before 10 p.m. ET at a residence on Knox Drive. Childress said detectives have found a couple of witnesses to the shooting and have determined a motive but did not want to release that information.

Smith used an emotional Instagram post to announce the news on Monday morning:

Smith starred at Lowndes County High School in Valdosta before signing with Florida State. He played four years with the Seminoles before the Jaguars selected him in the fifth round of the 2014 draft. Smith has started 33 games in three seasons with the Jaguars.

Smith, who is second on the team this season with 71 tackles, is expected to be away from the team for several days and it is unclear when he will return.

The Jaguars play at Detroit on Sunday.
