Brentford have signed Reading goalkeeper Ben Hamer and Chelsea defender Adrian Pettigrew on month-long loan deals.
Hamer, 19, has progressed through the Royals academy and signed professional terms last summer.
Reading manager Steve Coppell sent him out on loan to Crawley Town for most of last season.
Pettigrew, 20, is no stranger to Griffin Park having played there in the pre-season game last week.
