49ers vs. Broncos, preseason 2014: Practice squad watch picks up steam

The San Francisco 49ers have one preseason game under their belt, and with three remaining, the roster battles are heating up. I'll have an updated bubble watch this weekend, but we already know a lot of the long shots and weak bubble players. For many of them, the next three weeks are about earning a claim on the waiver wire at the end of camp, or a spot on the 49ers practice squad.

Here is a list of the players with practice squad eligibility. They are broken down by time in the league. 1st year players are those who have been in the league previous seasons, but did not accrue the necessary time to be considered a "second year player". If you think I'm missing anybody, or have a question about the eligibility of one I have listed, let me know in the comments.

I'll go into more detail later in the month, but for now, here is the CBA section covering practice squad eligibility (from Article 33):

Section 4. Eligibility:
(a) The Practice Squad shall consist of the following players, provided that they have not served more than two previous seasons on a Practice Squad: (i) players who do not have an Accrued Season of NFL experience; and (ii) free agent players who were on the Active List for fewer than nine regular season games during their only Ac­crued Season(s). An otherwise eligible player may be a Practice Squad player for a third season only if the Club by which he is employed that season has at least 53 players on its Active/Inactive List during the entire period of his employment.

A player shall be deemed to have served on a Practice Squad in a season if he has passed the club's physical and been a member of the club's Practice Squad for at least three regular season or postseason games during his first two Practice Squad seasons, and for at least one regular season or postseason game during his third Practice Squad season. (For purposes of this Section, a bye week counts as a game provided that the player is not terminated until after the regular season or postseason weekend in question.)
