Jered Weaver, who has been on the disabled list with a back strain since May 28, could return to the Angels this week. The right-hander is scheduled to throw a bullpen session on Sunday. Mike Scioscia said Weaver hasn't missed enough time to automatically require a rehabilitation start in the minor leagues. The manager said Weaver probably will throw 35-40 pitches Sunday after throwing 60 in the sharp simulated game that included his full arsenal of pitches. Said Scioscia: "If he throws a power 'pen,'" then returning directly to the big leagues "is doable, without a rehab start."
