The Raiders announced a couple of roster moves today. The team released tackle Larry Lancaster and traded linebacker Buddy Alliston to the Broncos in exchange for Denver’s eighth-round pick in the 1961 draft. Lancaster, picked off the Chargers’ roster in April during the allocation draft, had been well down the depth chart and his departure was no great surprise. Alliston hadn’t made a big splash either and now returned to the team that had him before he came to Oakland. That placed the current roster at 36 players.
