Yardling and jayvee sextets will take to the Arena ice against Governor Dummer and Audover tomorrow afternoon in the final tune-up scrimmages before the opening of the '47-'48 campaign.

Freshman mentor Stan Priddy will have four lines, five defense pairs, and four goalies ready for action against Dummer. Bob Di Blasio will play for Doug Anderson in the fast '51 first line of Anderson, Joe Kittredge, and Warren Carmen, although the change is not slated as permanent.

Preceding the Yardling face-off, the Jayvees will take on the same Andover squad that bowed to the Freshmen 12 to 2 last week. Line-ups are indefinite since several JV men have been moved up to the Varsity.

Defenseman Dick McDermott crashed into the boards in yesterday's practice and will be out of action this afternoon.
